I am not sure if I need to make a clone of my os and reinstall my os or just copy home?

I am contemplating a fresh install of my os, should I clone it or will just backing up the contents of my home directory allow me to transplant things across after the reinstall. This will not be a dual boot.

I found after installing a particular program things went awry, and is the sole motivation for reinstall.

Also is Gparted enough to get cloning done? Thanks in adavnce
